Weird Hybrid sound, sounds like a hum?

This happens rarely but when it does it sounds LOUD inside the cab and the outside too

Ya - not heard that before.
Unless I have like a weak version of it - not loud enough for in the cab yet.

Does it do it in reverse only?

HVAC condenser fan?

Cold morning and defrost on or hot and A/C on?

Doesn’t matter what drive mode. I notice cold weather brings it out

It’s subtle if you’ve got the windows up, but with windows down and radio off or low it’s loud.

From the outside it’s loud

To me...it sounds like the brakes/rotors like after you wash the truck and then move it. Maybe condensation on the rotors and the pads are squeak drying them off??? Just a thought

I heard a beep sound and it seemed to be keeping a nice beat, so maybe the car hums because it doesn't know the words? I am not smart enough about cars to really be able to help so I just post dumb stuff to try to make people laugh.....

If that video was my truck - you would have heard a loud squeak. My EB brake pads get dusty in my garage & almost always squeak on my initial backing out of garage.

That’s “normal” for my EB - but Hybrid brakes function differently? I’m with your idea…brake system related is my guess.

Along with the beeping and hum noises in reverse, I must say you have excellent skills backing up with that curved wall and narrow opening (that has an orange cone too). I don't know if I could manage that.

Sounds like the AC compressor kicking on to filter your Defroster air.
Maybe send that video to your dealer service.
